The new Chelsea manager struck a nerve with the forward when he said he was not the 'real' Ronaldo earlier in August -- referring to the Brazilian icon --with the Santiago Bernabeu star subsequently ruffled but wanting to stay out of a public spat.

Although Mourinho has since sought to clarify the issue, saying his initial quotes were blown out of proportion, Ronaldo is still refusing to answer questions regarding his fellow countryman and former manager.

"I will not mention the name of that person [Mourinho]," Ronaldo said to reporters following Portugal's 1-1 draw with Netherlands, in which he scored a late equalizer. "He's not worth it."

Ronaldo did, however, laud his current Blancos coach Carlo Ancelotti and says he is hoping that Madrid can complete La Decima and win back the Primera Division title from Barcelona this season.

"Ancelotti is a great coach, a great man and I am very happy to work with him," Ronaldo said. "We will try to win La Liga and the Champions League. It is difficult but this team is good, we have a great coach and we will try to make it happen."
